A module or device that generates control voltages with dynamic shapes, typically used for modulation, envelopes, or logic-based patching. Function generators are highly versatile tools in synthesis, capable of creating time-based events and shaping signals.
- Envelope Generation: Can create simple or complex ADSR-style envelopes for shaping amplitude, filter cutoff, or other parameters.
- LFO Creation: Functions as a low-frequency oscillator with adjustable shapes, including ramps, triangles, and exponential curves.
- Signal Processing: Modifies incoming signals by slewing (smoothing) or applying time-based transformations like attack and decay.
- Logic Functions: Can trigger events or generate gates by analyzing and responding to incoming signals.
For example:
- Patch a function generator to a VCA for dynamic volume control.
- Use it to add portamento (glide) between notes by smoothing pitch CV.
- Trigger looping mode to create repeating modulation patterns.
Function generators are indispensable for adding motion, shaping dynamics, and injecting life into modular patches.
